Abstract:
A torsional vibration damper hub for a vehicle clutch includes a first row of springs extending substantially in the clutch rotating direction and disposed in openings formed in a first inner annular plate and a first pair of outer annular plates; a second row of springs extending substantially in the clutch rotating direction and is disposed in openings formed in the second inner annular plate and the second pair of outer annular plates; the first and second row of the springs being arranged on a same radius from a center of rotation of the clutch; the springs in the first row of springs arranged in one first axial level are axially overlapping the springs in the second row of springs arranged in a second axial level with the purpose to decrease a total axial length of the clutch. In an alternative embodiment the damper hub is substantially identical to a dual damper hub in conventional twin-plate clutches.
